Limoniinae crane flies (Diptera: Limoniidae) new to Korea

Investigations of Limoniinae (Diptera: Limoniidae) crane flies on the Korean Peninsula were initiated by S. Podenas and H.-W. Byun in 2012. Since then, crane flies have been collected annually in different localities, at different times and using different methods throughout the country. The aim of the study was to document, redescribe, illustrate, and prepare keys for all Korean crane fly species identified to date. This publication is a continuation of our previous work on Limoniinae crane flies in Korea. This study covers the genera Atypophthalmus Brunetti, 1911 and Thrypticomyia Skuse, 1890, which are new records for the Korean Peninsula. New findings of Achyrolimonia Alexander, 1965, Helius Lepeletier and Serville, 1828 (Latreille et al., 1828) and Limonia Meigen, 1803 are discussed. Despite original and subsequent descriptions of species of the genera Atypophthalmus and Thrypticomyia species over a long period of time, some species were known only from original descriptions and no illustrations were available. In this article, we provide photographs of both sexes of Atypophthalmus (Atypophthalmus) crinitus (Alexander, 1924), and female specimens of A. (A.) stylacanthus (Alexander, 1971), A. (Microlimonia) inelegans (Alexander, 1924), A. (M.) machidai (Alexander, 1921). A wing and female specimen of Thrypticomyia unisetosa unisetosa (Alexander, 1929) are also presented for the first time on record.
